ABSTRACT:
Cytotoxic effects associated with ground fractured silica-containing minerals and silicates, including asbestos, are prevented by coating the silica-containing minerals and silicates with an aqueous solution containing an aqueously compatible silane coupling agent so that a monomolecular film is formed on the surface of the silica-containing minerals and silicates.
